Frisk's words fell on deaf ears, it was a talent Sans had grown to nurture(for better or worse), and as she scolded him, he just tuned her out. And then she spoke of how little trust he had, and the skeleton couldn't hold back a flinch. She was right, he didn't trust anyone, not now, maybe not ever again, at least in some aspects.

He trusted Frisk around everyone else, trusted that she wasn't who she used to be, trusted that even when they all reached the surface, she'd be a monster at heart. Alphys, he trusted to break them out of this cave, Tori to be the mother most none of the monsters down here never had, Undyne to protect everyone from any murderous humans, and Papyrus to spread joy that they so often seemed to need. But he didn't trust them with things they couldn't understand. The resets, all of their timeless deaths, the truth about Flowey, all of the humans, all of it. They would never remember, so there was no point.

He'd told Paps before, broken down entirely after about the fiftieth reset and spilled everything. And Papyrus naturally accepted his words, though not without question, and Sans answered them all. But...

"heh, it's kind of pointless if they won't remember... do you even know how many times i've told paps everything? about the resets, what really happened, why i'm so messed up..... four hundred fifty two times. after that i gave up. there's nothing i can do to stop all of this from happening, and i don't want any of them to worry over it. i.... i-i'm supposed to protect them from the things they don't understand, ya know? this... it's not any different. i just-! ............ it's... simpler if it's just me," he worded delicately, bones rattling a bit louder.

He took a shaky breath, feeling lightheaded, but he didn't care. Right now panic was quickly rising in his chest, and he couldn't stop thinking about the absolute sense of hopelessness overwhelming him. Like he was back in the prior resets, just waiting for the next one to happen.

"it's not that i don't trust you or the others, it's just... it's so much easier to take all of the pain than to watch anyone else go through it...."
